MORRISON – Twice-convicted killer Nicholas T. Sheley pleaded not guilty Monday to murdering four people in a Rock Falls apartment in late June 2008.

Sheley is tentatively set to stand trial June 3 in the deaths of Brock Branson, 29; his fiancée Kilynna Blake, 20; her 2-year-old son, Dayan; and Kenneth Ulve, 25.

During a short hearing Monday, Assistant Attorney General Michael Atterberry said prosecutors expect to file a motion asking to keep Sheley shackled during pretrial hearings and another motion seeking to admit information on prior bad acts at trial.
